About

After learning a bit of programming, I was attracted by the networking world. I got from petty Pascal/C++ projects through web development using PHP and later Python, to a freelancing work with most of the projects in server administration, network equipment configuration and a bit of programming. Most people in the business know me from my conference talks and articles.

One of my conference talk brought me an offer from Red Hat, which I joined in May 2012 to work on NetworkManager. I was already a Fedora user and package maintainer at that time. Since August 2013 I'm no longer working as a regular NetworkManager developer (staying an upstream contributor, though). Since then I am working on various networking related projects including dual-stack networking and DNSSEC features. I'm also interested in various network-related standards and especially bugs and bad assumptions in IETF documents.

Simple maintainance tasks

Make a fix and a build

bug=123456
message="do something"

# ... add/modify files ...
rpmdev-bumpspec *.spec -c "Resolves: #$bug - $message"
fedpkg commit -c
# ... check using gitk ...
fedpkg push && fedpkg build

Make a scratch build from locally generated SRPM

fedpkg build --scratch --srpm

Bump a rawhide package to a newer version

In the package git directory:

version=...

# Prepare a commit
fedpkg switch-branch master
rpmdev-bumpspec --new="$version" --comment="new version $version" *.spec
spectool -g *.spec && fedpkg new-sources `spectool -l *.spec | grep / | sed 's/.*\///'`
fedpkg commit -c

# Test it
fedpkg build --scratch --srpm

# Create a public build
fedpkg push && fedpkg build

Requires development version, see:

Prepare rawhide to replace branches

Warning: This method discards changes in all branches and should only be used after all of the important changes are incorporated into master. Also, it is only suitable for packages where it's practical to maintain the same version in branches as in rawhide.

branches="f20 f19"

# Fake-merge all branches into master:
for branch in $branches; do
    fedpkg switch-branch master
    git merge -s ours $branch
done

# Build a new release
rpmdev-bumpspec
fedpkg commit -c
fedpkg push
fedpkg build

Update branches to match rawhide and build them

Use the above technique to prepare rawhide if branches can't be fast forwarded to rawhide.

branches="f21 f20"

# Fast-forward all branches to master HEAD:
for branch in $branches; do
    fedpkg switch-branch $branch
    git merge --ff-only master
    fedpkg push
    fedpkg build --nowait
done

# Switch back to master
fedpkg switch-branch master

Issue updates

branches="f21 f20"
type=bugfix
bugs=
comment="Bug fix update."

# Create updates for all branches
for branch in $branches; do
    fedpkg switch-branch $branch
    bodhi --new --type="$type" --bugs="$bugs" --notes="$comment" --close-bugs `fedpkg verrel`
done

# Switch back to master
fedpkg switch-branch master

Patchwork

Using vim

Open three panes containing (1) patch to be edited, (2) patched file and (3) rejected hunks.

package=...
version=...
patch=...
file=...

vim -O $patch $package-$version/$file{,.rej}

Using git

Warning: Untested. I used a similar command but lost it.


package=...
version=...
dir=/path/to/upstream/workdir

(echo cd $dir; for patch in `awk '/^Patch[0-9]*: / { print $2 }' *.spec`; do echo -n "git apply --index "; realpath $patch; echo git commit -m $patch; done) | sh

New package

Create a local Git repository

package=...
editor=...

git init $package
cd $package

$editor $package.spec
git add $package.spec

fedpkg new-sources `spectool -l *.spec | grep / | sed 's/.*\///'`

rpmdev-bumpspec $package.spec -m 'initial build'
fedpkg commit -c

Create a review request

rawhide=f22

fedpkg --dist $rawhide srpm
fedora-create-review --no-scratch-build *.spec *.src.rpm

Update a review request

rawhide=f22
message="incorporated review feedback"

rpmdev-bumpspec *.spec -m "$message"
fedpkg commit -c

fedpkg --dist $rawhide srpm
fedora-create-review --amend --no-scratch-build *.spec *.src.rpm

Requires:

Review a new package

System configuration:

yum install @fedora-packager fedora-review
ln -s /etc/mock/fedora-devel-x86_64.cfg /etc/mock/default.cfg

mockuser=...

usermod -a -G mock $mockuser

Review local files:

name=...

fedora-review -n $name

Review bugzilla:

bz=...

fedora-review -b $bz
